Maintenance (continued)
WARNING:
Brewer should be unplugged from
electrical outlet before any service is performed.
CRITICAL COMPONENTS TESTS (CONTINUED)
B) Probe Test
If lack of water persists, check the probe as follows:
1. Turn on the power and water supply. Check inside
the tank to make sure the water is not touching the
Probe.
2. Pull wire and terminal out of the Probe rod.
3. If water still does not flow after the wire is
disconnected from the Probe, the problem may be
in the Solid State Water Level Control Board.
4. If water starts flowing into the tank, the Probe may
be grounded, due to excessive liming. Check with
ohmmeter. Clean or replace probe.
C) Solid State Water Level Control Board Test
Check the board as follows:
1. Make sure there is power input to the board at the
terminals 2 & 3. Your voltmeter should read 115
Volts. It should read the same at terminals 1 & 3. This
is the output power to electrify the coil of the
Solenoid Valve to open it. The lack of voltage at
terminals 2 & 4 will indicate that the board is not
working properly.
2. Make sure all wire connections to the board are
tight.

3. The grounding plate at the top, in the back of the
board, should be securely grounded. The board will
not work or will work erratically if it is not grounded
properly.
4. If after this, the Controller is still failing to open the
Water Inlet Valve, replace the Water Level Control
Board.
